Organic phase change materials (PCMs) have been widely studied for thermal management applications, such as the passive cooling of silicon photovoltaic (PV) cells, whose efficiency is negatively affected by rising temperature. The aim present study to investigate shape stabilization PCMs using expanded graphite (EG) a highly conductive supporting matrix, leading development novel PCM/EG composites with melting temperatures in range 30–50 °C. Different organic were selected and compared, i.e., two paraffins eutectic mixture fatty acids (myristic palmitic acid). EG was vacuum-impregnated PCMs, and, subsequently, powdery cold-compacted obtain dense heat-absorbing panels. conductivity enhanced up 6 W/m·K, guaranteeing enthalpy 160 220 J/g. This found that vacuum impregnation method suitable PCM stabilization, cold compaction allows formation solid panels improved response. obtained utilized produce about × 2 cm3, PV.
